Pair of heart shaped swivel fastening cufflinks. The heart is of a black onyx looking material. Rest of the cufflink is of silver coloured metal. Possibly silver or sterling silver, unsure. Quality is very good and the links are unblemished. The box is slightly worn on outside. Worn only a few times. I purchased these as a gift for my ex spouse a few years ago and he left them in my possession when he left. Suitable for white collar or formal wear. These are nice links. Shipping £2.80 tracked.
